| dc.description.abstract | <p>The upper critical fields H-c2(T) of single crystals of Sr1-xEux(Fe0.89Co0.11)(2)As-2 (x = 0.20 and 0.46) were determined by radio-frequency penetration depth measurements in pulsed magnetic fields. H-c2(T) approaches the Pauli limiting field but shows an upward curvature with an enhancement from the orbital limited field, as inferred from the Werthamer-Helfand-Hohenberg theory. We discuss the temperature dependence of the upper critical fields and the decreasing anisotropy using a two-band BCS model.</p> | |
